Embodiment 1

[0076] An improved detection device for the shear deformation of road and bridge rubber bearings with the above-mentioned design structure needs to be installed as a backup before it is used.

[0077] During installation, first, the operator assembles the clamping assembly 2, which includes a fixed plate 21 symmetrically arranged under one side of the box body 1, and the two fixed plates 21 are connected with a guide rod 22 with a fixed collar 23, and the guide rod The other end of 22 is connected with movable collar 24, and the same end of fixed collar 23 and movable collar 24 all connects the extruded plate 25 with anti-skid pad 27 inboard by connecting rod, passes through bolt between two extruded plates 25 Component 26 is connected. The two extrusion plates 25 are symmetrical to each other.

[0078] Then, the operator installs the box 1 . One side of the box body 1 is provided with an electric storage device 3, and the bottom is provided with a control switch 5, both of ...

Embodiment 2

[0087]The design structure of embodiment 2 is basically the same as that of embodiment 1, the only difference is that the overall structure of the detection assembly 4 is different. The detection assembly 4 of this structure includes a sliding mounting plate 4a, an electric push rod 4b, a detection protractor 4c and an indicator Needle 4d and measuring ruler 4e, wherein, one side of sliding mounting plate 4a is connected with electric push rod 4b, and electric push rod 4b is electrically connected to electric storage device 3, and electric storage device 3 is electrically connected to control switch 5 through wire;

[0088] The other side of the sliding mounting plate 4a is provided with a detection protractor 4c, the detection protractor 4c is provided with an indicator needle 4d, and one side of the indicator needle 4d is connected with a measuring ruler 4e.

[0089] The electric push rod 4b is installed on the support plate 41;

[0090] The detection protractor 4c has a sem...

Embodiment 3

[0097] The design and structure of embodiment 3 and embodiment 1 and embodiment 2 are basically the same, and the only difference is that the four corners of the bottom of the box body 1 are also provided with a moving device 13, and the moving device 13 is a directional wheel or a universal wheel. The directional wheel or the universal wheel are provided with a braking device matched with it to complete the work.

[0098] The design of the structure realizes the flexible and convenient movement during the actual working process, and reduces the labor intensity of the operator to the greatest extent;

[0099] The specific installation and use are the same as in Embodiment 1 and Embodiment 2, and will not be repeated here.

Description

technical field [0001] The invention relates to a detection device, in particular to an improved detection device for shear deformation of road and bridge rubber bearings, which belongs to the technical field of bridge engineering detection. Background technique [0002] The rubber bearing is a bridge bearing product made of multi-layer natural rubber and thin steel plate inlaid, bonded and vulcanized. This type of rubber bearing has sufficient vertical stiffness to withstand vertical loads, and can reliably transmit the pressure of the superstructure to the abutment; it has good elasticity to adapt to the rotation of the beam end; it has large shear deformation to Meet the horizontal displacement of the superstructure. [0003] As a kind of rubber bearing, the plate rubber bearing is susceptible to shear deformation caused by the horizontal force of the bridge. At present, the inspection methods for the shear deformation of road bridge rubber bearings are mainly manual vis...
